Yes I have adjusted the limit screws ... no problem with the chain going to far either way.
I just have the "trim" issue.
Are we talking about the chain rubbing against the front derailleur when on the big ring?
if so which cog(s) is the chain on when this happens?
Sometimes a re-alignment of the derailleur can fix this.
I'm thinking you really shouldn't have chainrub on the derailleur when on the big ring unless you are cross-chained to the biggest cassette cog.
Compact doubles often have chainrub on the side of the big ring with the chain running on the inner chainirng and smaller cogs, especially if the inner ring is a 34. This can be partially corrected with a bottom bracket spacer.
